I have a friend that wants to sell me his old Wii but i can't test it now so i can't really know what kind of boot1 have and if i can install bootmii as boot2 i only have this serial LU5563XXXX-X wich have a GC2-D2C (v1) drive on it. Could someone help to know if i can install bootmii as boot2 in this Wii and if i can run backup games from neogamma? Thanks for your time.

the only way to do so on new wiis would be:
(1) find a new boot 1 exploit (doubt it would happen)
(2) do some wired hardmod that replaces the boot0-4 chip
0r (3) if you have a "insert startup disc" wii then if you went to the nintendo main building and jacked a boot1 V1 CD then you could.
